  20 /* Add any extra modes needed to represent the condition code.
  21
  22    On the Visium, we have a "no-overflow" mode which is used when arithmetic
  23    instructions set the condition code.  Different branches are used in this
  24    case for some operations.
  25
  26    We also have a "bit-test" mode which is used when the bit-test instruction
  27    sets the condition code.
  28
  29    We also have two modes to indicate that the condition code is set by the
  30    the floating-point unit.  One for comparisons which generate an exception
  31    if the result is unordered (CCFPEmode) and one for comparisons which never
  32    generate such an exception (CCFPmode).  */
